Experience the Comfort of a Dual Fuel System. You want to keep your home comfortable without outrageous energy costs, which is why you purchase high efficiency HVAC products. What you might not have known is that some of these products are not only energy efficient when operating themselves, but they can be combined to produce even greater efficiency to your family. At Hammack Service Company in Richardson, we have furnaces that work with heat pumps to create a dual fuel system. Combining a gas furnace with an electric heat pump gives you the ability to use two different fuel types: gas and electricity. Once the temperature becomes too cold for your heat pump to run efficiently (usually around 32 degrees Fahrenheit), the furnace starts up to provide the rest of the power you need to stay cozy. That means you’re only using gas fuel when it’s needed. Dual fuel systems switch between the two types of heat, which optimizes energy uses and minimizes heating costs. That’s a solution we like to see. Explore our gas furnace and heat pump offerings to find details about each system.
